This blog follows the progress of restoring and converting a 1973 Porsche 914 from stock to full electric drive, with an electric motor and half a ton of batteries. Now that the car is done and in storage while I live overseas, I'm adding descriptions and pictures of each Tesla location I visit.

Tach sensor

The Electro Automotive kit comes with no provision for a device to collect motor RPM data. They do have the tach wire terminate on a block in the rear contactor area. While I was at EVCCON, I saw the WarP Speed Sensor from ReChargeCar. The picture I took of my unit is horribly out of focus, so I've copied the one from the ReChargeCar web site.
